Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584698, here are decompositions:

31 + 31584667 = 31584698
97 + 31584601 = 31584698
139 + 31584559 = 31584698
151 + 31584547 = 31584698
157 + 31584541 = 31584698
199 + 31584499 = 31584698
241 + 31584457 = 31584698
337 + 31584361 = 31584698

Showing the first eight; more decompositions exist.
